The amount of currently available digital information grows rapidly. Relevant information is often spread over different information sources. An efficient and flexible framework to allow users to satisfy ef- fectively their information needs is required. The work presented in this paper describes SIMS (Semantic Information Management System), a ref- erence architecture for a framework performing semantic annotation, search and retrieval of information from multiple sources. The work pre- sented in this paper focuses on a specific SIMS module, the SIMS Semantic Content Navigator, proposing an algorithm and the related implementa- tion to calculate a semantic similarity measure inside an OWL ontology. This measure is based on ontology structure and on the information pro- vided by attributes and relations that are defined inside the ontology. This work is the result of a collaborative effort between the DINFO (Depart- ment of Computer Science and Engineering) and the research team of En- gineering - Ingegneria Informatica.
